| Abstract: | In order to solve the problem about multi-point temperature measurement, we used the temperature measurement system which is combined by digital temperature sensor chips, DS18B20, 51 MCU, RS232 serial port. It has high precision, multi-point distribution, and could remote monitoring features. All of that could satisfy the orders. This article focuses on the basic method about single-bus digital temperature sensor DS 18B20 and the key technology about automatic search algorithm. |
